Fluorine-containing garnet-structure lithium ion oxide ceramic
The invention relates to fluorine-containing garnet-structure lithium ion oxide ceramic. A lithium-lanthanum-zirconium oxide (LLZO) having a garnet crystal structure is provided. The fluorine content of the lithium-lanthanum-zirconium oxide can be 40 mol%. The fluorine can be a lithium-containing compound, such as lithium fluoride, can be adopted as a sintering aid, and can promote formation of cubic-phase garnet. The sintered oxide can be compact ceramic, and the ceramic comprises a large number of dispersed closed pores. The ionic conductivity of a solid electrolyte membrane containing the oxide can be at least 1*10<-4> S/cm.
